BACKGROUND OF THE INVENTION A. Field of the Invention

The present invention relates to a combination of ingredients that can be used to treat or prevent erythema (i.e., reddened/flushed skin) in people having sensitive skin. This combination of ingredients can be included in a wide-range of product formulations (e.g., toners, gels, masks, etc.).

B. Description of Related Art

Sensitive skin is a condition where the skin has a tendency towards flushing, reddening, or blushing (i.e., erythema) when exposed to stimuli such as UV light, heat, cold, chemicals, or active ingredients in skin formulations, etc. One of the issues in the cosmetics industry is that active ingredients known to potentially cause erythema in sensitive skin are needed to treat a given skin condition such as fine lines and wrinkles, sagging skin, acne, etc. Therefore, people with sensitive skin either have to avoid such products or end up purchasing additional products that can help alleviate the aforementioned symptoms associated with sensitive skin.

SUMMARY OF THE INVENTION

The present invention offers a solution to the aforementioned problems. The solution is premised on a discovery of a combination of ingredients—hydrolyzed algin, escin, Ruscus aculeatus root extract, ammonium glycyrrhizate, Centella asiatica extract, hydrolyzed yeast protein, and Calendula officinalis flower extract—that can be used to alleviate or even prevent symptoms associated with sensitive skin (e.g., erythema or skin inflammation). This combination of ingredients can be used in a variety of product formulations (e.g., toners, cleansers, emulsions such as lotions or creams, masks, gels, etc.) along with other skin-active ingredients that are known to cause erythema when applied to sensitive skin. That is to say, this combination of ingredients can be used with other known skin-active ingredients so as to treat a given skin condition (e.g., with the known skin active) and prevent or reduce the symptoms associated with sensitive skin (e.g., with the aforementioned combination of ingredients). Without wishing to be bound by theory, it is believed that the discovered combination of ingredients provides for a strong anti-oxidative effect (see Examples) and/or which interferes with various steps in the inflammatory process/cascade, thereby reducing the flushing/blushing/reddening that is typically seen with sensitive skin.

In one instance, there is disclosed a topical skin composition comprising a combination of hydrolyzed algin, escin, Ruscus aculeatus root extract, ammonium glycyrrhizate, Centella asiatica extract, hydrolyzed yeast protein, and Calendula officinalis flower extract.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

People afflicted with sensitive skin are susceptible to skin reactions with current products on the market that include active ingredients targeted towards a specific skin condition such as fine lines and wrinkles, loss of elasticity, hyperpigmentation, melasma, dry skin, oily skin, acne, etc. While treatment of a particular skin condition can be beneficial, it can also result in adverse effects such as producing reddened or inflamed skin in people that have sensitive skin. The present invention offers a solution to this problem by providing a combination of ingredients that can be used on sensitive skin without producing a skin-irritating reaction such as erythema/reddening of the skin.

These and other non-limiting aspects of the present invention are provided in the following subsections.

Example 1 Efficacy of Ingredients

Inhibition of Pro-Inflammatory Cytokines

Hydrolyzed algin was found to inhibit production of a variety of pro-inflammatory cytokines in primary adult human keratinocytes (Cascade # C-005-5C) using a MesoScale Discovery SECTOR Imager 2400. The Imager 2400 was used to detect and calculate the amount of a selected pro-inflammatory cytokine present in a sample. A summary of these data are provided in Table 1.

TABLE 1* Pro-Inflammatory Cytokine % Change From Control** TNF-α −37 IL-6 −70 IL-8 −33 IL-10 −40 IL-12 p40 −32 GM-CSF −28 *1% hydrolyzed algin was used and was obtained from Barnet Products Corporation under the trade name Phyko-AL-PF. **Control used was 0.5% DMSO. % Change From Control = % Pro-inflammatory Cytokine − % Pro-Inflammatory Cytokine of Control. Therefore, a negative (−) indicates inhibition of cytokine production.

The procedure used to obtain the data in Table 1 included the following steps:

-   -   Cell Culture—HEKa: HEKa cells were grown to subconfluence from a         frozen vial in 3×T75 tissue culture flasks (37° C., 5% CO2).         Confluent T75s (P1-P3) were washed with HBSS then trypsinized         with 1.5 ml trypsin for ˜4 min at 37° C. Cells were collected in         4 ml TNS, then spin in 15 ml conical tubes and resuspended in         Epilife media and plate in 6 well dishes. Test compounds were         diluted to 1% and 0.1% in media+10 ng/ml PMA. Upon reaching 85%         confluence, the cells were washed and the media was replaced         with 2 ml diluted test compound for 4-6 hrs (37° C., 5% CO2). 2         ml media was collected from each well, aliquot, and freeze at         −80° C. until assayed with Procollagen peptide kit (PIP). All         media was removed from cells, and 1 mL diluted MTS reagent was         added to each well, incubated for 15-30 min (37° C., 5% CO2),         and the plate was read at 490 nm.     -   Step 1: Samples may not require dilution prior to use in the         assay. Bring appropriate diluents and plates to room temperature         and thaw cytokine calibrators on ice. Store detection antibody         mix at 4° C.; shield from light. Prepare calibrator solutions         and calibration curve. (If applicable). Use the 1 μg/mL         calibrator stock to prepare an 8-point calibration curve of         10,000, 2500, 625, 156, 39, 9.8, 2.4, and 0 pg/mL. The         calibration curve can be modified as necessary to meet specific         assay requirements. Prepare Detection Antibody Solution by         diluting the Detection Antibody to 1 μg/mL in 3.0 mL of HSC.         Antibody Diluent (per plate) (serum/plasma samples), or Antibody         Diluent (tissue culture samples). Keep this reagent in the dark.         Prepare 25 mL of 2× Read Buffer T by diluting 4× Read Buffer T         1:2 with deionized water. Continue with assay using appropriate         protocol below.     -   Step 2: For MULTI-SPOT Assays with IFN-γ, Dispense 150 μL/well         1% Blocker B Solution. For MULTI-SPOT Assays with IL-12p40,         dispense 150 μL/well 0.1% Blocker B Solution. Incubate at room         temperature with vigorous shaking (300-1000 rpm) for 1 hour.         Wash plate 3× with PBS or other standard buffer. Dispense 25         μL/well Calibrator or Sample. Incubate at room temperature with         vigorous shaking (300-1000 rpm) for 1-2 hours.     -   Step 3: Dispense 25 μL/well 1 μg/mL Detection Antibody Solution.         Incubate at room temperature with vigorous shaking (300-1000         rpm) for 1-2 hours.     -   Step 4: Wash plate 3× with PBS-0.05% Tween-20. Dispense 150         μL/well 2× Read Buffer T. Analyze plate on SECTOR Imager 2400         instrument.         Inhibition of CGRP Production

Hydrolyzed algin was found to inhibit production of CGRP by human epidermal keratinocytes. The endpoint of this assay is direct detection array analyzed by the Meso Scale Discovery system SECTOR 2400 Imager. The Imager 2400 was used to detect and calculate the amount of a CGRP present in a sample. A similar procedure to that used in the Inhibition of Pro-Inflammatory Cytokines assay above was used to find that a 1% hydrolyzed algin blend inhibits CGRP production in primary adult human keratinocytes (Cascade # C-005-5C). An average inhibition of 65.70% over control was seen.

Antioxidative Properties

A blend of Escin, Ruscus aculeatus root extract, Centella asiatica extract, Hydrolyzed yeast protein, Calendula officinalis flower extract, and Ammonium glycyrrhizate was found to have antioxidative properties using the Oxygen Radical Absorption Capacity (ORAC) assay (Zen-Bio ORAC Anti-oxidant Assay kit (# AOX-2)). This assay measures the loss of fluorescein fluorescence over time due to the peroxyl-radical formation by the breakdown of AAPH (2,2′-axobis-2-methyl propanimidamide, dihydrochloride). Trolox, a water soluble vitamin E analog, serves as positive control inhibition fluorescein decay in a dose dependent manner. A summary of these data are provided in Table 2.

TABLE 2* % Better than 100 μM Blend Amount Trolox % Better than Untreated  0.1% 201.31 276.21  0.01% 48.69 136.31 0.001% −73.80 24.02 *Blend of Escin, Ruscus aculeatus root extract, Centella asiatica extract, Hydrolyzed yeast protein, Calendula officinalis flower extract, and Ammonium glycyrrhizate used was Biophytex ™ LS 9832 and can be obtained from BASF Care Creations.

The procedure used to obtain the data in Table 2 included the following steps:

-   -   Step 1: Warm the plate reader incubation chamber to 37° C.         Set-up plate reader to perform a kinetic read for 30 minutes         with 1 minute intervals. Excitation=480 nm; Emission=520 nm.     -   Step 2: Prepare fluorescein working solution from the stock         solution provided by transferring 16.8m1 of Assay Buffer to an         empty tube (not provided) and adding 1.2 ml stock fluorescein         solution. Mix and protect from light.     -   Step 3: Prepare Trolox standards as follows: Briefly spin down         the contents of the 1.5 mM Trolox standard tube after thawing.         Pipette 580 μl of Assay Buffer into the 1.5 mM Trolox standard         tube provided and mix well by vortexing. This produces a diluted         stock Trolox standard of 50 M. Pipette 50 μl of assay buffer         into 6 tubes. Using the newly diluted stock Trolox solution,         prepare a dilution series. Mix each new dilution thoroughly         before proceeding to the next. The 50 M stock dilution serves as         the highest standard, and the assay buffer serves as the zero         standard.     -   Step 4: Add 150 μl of the working fluorescein solution to each         well of the assay plate provided.     -   Step 5: Add 25 μl of samples or Trolox standards to individual         wells of the assay plate provided, add 25 μl of assay buffer to         individual wells as a negative control. Place plate at 37° C.         for at least 5 minutes.     -   Step 6: While the assay plate is equilibrating to 37° C.,         prepare the AAPH Working Solution by adding 2.7 ml Assay Buffer         to the tube provided and gently invert. Place the working         solution on ice until needed. AAPH solution is good for 8 hours         if kept on ice.     -   Step 7: To begin the assay, add 25 μl of the AAPH working         solution to each of the wells containing standards and samples         from step 5. Place the assay plate in the plate reader and begin         kinetic fluorescence reading.
